From 32875eb1f3b928dfe63c5752e8152a9dc09928f3 Mon Sep 17 00:00:00 2001 From: "H.J. Lu" Date: Wed, 10 Feb 2016 19:33:52 -0800 Subject: [PATCH] Mask off the least significant bit in GOT offset The least significant bit in GOT offset is to record whether we have initialized the GOT entry in R_386_GOT32 processing. We need to mask it off for R_386_GOT32X.
